How to draw a sign of thunderstorm weather

Thunderstorm weather icon is as follows:

Draw clouds first, and draw with wavy lines. Add an expression to the cloud. Two little hands are drawing clouds. Draw lightning. Lightning flashed through the clouds. Pay attention to the mutual penetration of clouds and lightning. Color it, and simple and beautiful light will be drawn.

Conditions for the formation of lightning:

Lightning is a discharge phenomenon in thunderstorm clouds. Thunderstorm clouds generally have two conditions, sufficient water vapor and strong convection. In winter, because the air is cold and dry, the solar radiation is weak, and convection is not easy to form in the air, so lightning is rare.

But sometimes when the temperature is high in winter, it will form thunderstorm clouds, leading to lightning and rain and snow. Convection is particularly strong, and it can also form hail, which will produce the weather phenomenon of "thunder in winter". Knowing these reasons, it is not surprising that it thunders in winter.

Thunder is a natural phenomenon. When it rains, some clouds in the sky are positive and some are negative. When two kinds of clouds meet, they will emit lightning and a lot of heat, which will make the surrounding air heat and expand. Instantly heated and expanded air will push the surrounding air and produce strong explosion vibration. This is thunder.

Thunderstorms are caused by strong convection of warm and humid air in some places. The sharp rise of warm air produces the violent vibration of cumulonimbus clouds, which will accumulate a lot of charges and produce lightning.

Indoor lightning protection

1, when lightning strikes, pay special attention to: turn off the computer, cut off the power supply (unplug the main power cord of the main chassis from the patch panel, completely cut off the power supply), and unplug the network cable (sometimes this is ignored).

2. When lightning strikes, try to cut off all the power in your home. Lightning protection experts reminded that only in this way can it be safer. When buying a new house, pay attention to whether the house has lightning protection facilities and check the lightning protection acceptance certificate. Before the thunderstorm comes, close all doors and windows to prevent the ball thunder from invading.

3. Stay away from all kinds of cables and metal pipes in lightning weather, do not surf the Internet, make phone calls or watch TV, and cut off all power supplies as much as possible. Don't go near the wall, don't take a bath, especially don't use a solar water heater. Computers and household appliances are best placed against the wall.
